Types of Furnace: Vacuum Furnace

A furnace is a device that is used for heating, such as the extraction of metals from ores or smelting or in oil refineries and other chemical plants, for example, as a heat source for fractional distillation pipe. The heat energy to fuel the furnace obtained from burning fuels, through electricity such as electric arc furnaces, or by heating in an induction furnace Induction. Furnaces are available in several different types and a vacuum furnace is one of them. For those who still do not know what it means by a vacuum furnace, in this article, we will present a little explanation about it for you.

Vacuum furnace

The vacuum furnace is one of the types of furnaces that heat the material, usually metal, at a temperature degree which is very high and carries out processes such as heat treatment, sintering and brazing using low contamination and high consistency. The inside part of a vacuum furnace is circled by a vacuum. The deficiency of air or other gasses prevent heat transfer to the product through convection and eliminate the source of contamination.

Heating the metal to a high temperature usually causes rapid oxidation, which is not cold down. The vacuum furnace is the one to remove oxygen and prevent this from happening. The gas insert, such as argon, is usually used to accelerate the cooling of the metal to return to the level of non-metallurgical or below 400 ° F following the process which is wanted in the furnace.

This type of furnace has several benefits to offer and some of the benefits of the vacuum furnace are as follows:
– The range of the temperature is of 2000-2800 ° F (1100-1500 ° C)
– The temperature can be maintained within a small area
– Contamination of carbon-oxygen and other gasses at low product
– Rapid cooling products
– The process can be computer-controlled to ensure a repeat of the phase-in metallurgy.
